Question 1. I want to know how to do a hierarchical regression for a censored-inflation model. From example 3.3 (page 22) lets say that I want to add variable X4 in the second step.

#STEP 1#. Model y1 ON x1 x3 y1#1 ON x1 x3 #Step 2#. ?????

how would I tell the program to do this.

Question 2. Is it possible to have a multivariate censored regression where several dependent censored variables are regressed onto a set of predictors simultaneously. If so how would I specify this in the exmaple above for the additional dependent of y1 for example?
